ADJUSTABLE COMBINED WOOD AND COAL HEATER.

Specification of Letters Patent.

Patented May 14, 1918.

Application filed February 25, 1915. Serial No. 10,630.

To all whom it may concern:

Be it lniown that I, DAVID QUINCY MINAR, a citizen of the United States,residing at Upland, in San Bernardino Co. and State of California, haveinvented a new and useful Improvement in or for Any and All Air-TightHeating-Stoves, the title of which is the Adjustable Combined lVood andCoal Heaters, of which the following is a specification.

The primary object of this invention is to improve the construction ofthe modern wood burning stove, by permitting of the stove beingconverted, at will, from a wood burning stove to a coal burning stove,and vice versa.

Another object of the invention is to provide an attachment for woodburning stoves that will permit of the above object being carried out,that will be cheap to manufacture, will be eiiicient in operation,durable, and which can be readily applied to the stove withoutnecessitating alteration of the stove.

Other objects will appear and be better understood from that embodimentof my invention of which the following is a specification, referencebeing had to the accompanying drawings, forming a part thereof, in whichFigure 1 is a vertical sectional elevation of the stove, with theattachment applied thereto,

Fig. 2 is a horizontal section taken on the line 22 of Fig. 1, andlooking in the direction of the arrows.

Referring to the drawings, the letter A designates a wood burning stoveof ordinary construction, having the top wall provided with the usualentrance opening B, and the flue opening 0, the bottom of the stove having, in this instance, a circular cut-out portion so as to Provide anopening D, and the lower ends of the side walls of the stove projectinga slight distance below the bottom wall to provide a flange E.

The attachment for the stove consists of an inverted substantiallyfrusto-conical firepot l, which has its opposite ends open and itssmaller end positioned directly over the opening D in the bottom wall ofthe stove, as shown in Fig. 1, the said fire-pot being provided at thesmaller end thereof with laterally and outwardly extending cars, whichtral cross bar of the grate has formed there on a depending integral lug7, which projects through the opening D.

Suspended from the lower side of the bottom of the stove, and beneaththe opening D, is a rectangular shaped ash-pit 8, the outer end of whichprojects a slight distance beyond the front of the stove. The

iash-pit 8 includes the side walls 9, bottom wall 10 and rear or innerwall 11, the top of the ash-pit and the forward end being open and theupper edges of the side and end walls being extended laterally toprovide an attaching flange 12 adapted for connection to the stovebottom, by means of bolts 18 which extend through the stove bottom andthe flange, so as to hold the ash-pit in place.

Slidably mounted within the ash-pit is a substantially rectanglar shapedash receiving receptacle 1 1, which is of a length and widthsubstantially equal to the length and width of the ash pit, and includesa bottom wall 15, side walls 16, and front wall 17, the top of thereceptacle being open and underlying the grate 6, and the inner end ofthe receptacle being open, so as to permit of the said inner end of thereceptacle passing the lug 7 when the receptacle is being inserted intothe ash-pit or removed therefrom. When the receptacle is positionedwithin the ash pit, the outer or end wall 17 serves as a closure for thefront or outer end of the ashpit, and the said outer wall of thereceptacle has its upper edge provided with a rearwardly extendingflange 18, which partially overlies the interior of the receptacle, andhas its forward edge curved, as at 19. A handle 27 is rigidly connectedon the said wall 17 of the receptacle and serves as means by which thereceptacle can be withdrawn from. the ash-pit.

A grate shaker 28 extends through a slot 29 in the flange E of thestove, and into the receptacle 1 1, and has its inner end bifurcated,for the reception of the lug 7 of the grate, said bifurcated end of theshaker resting upon a pin 30 which extends through the lower end of thelug T. The opposite end of the shaker extends up Wardly, as at 31, andabove the receptacle, to provide a nianipulating' handle, When it isdesired to shake the grate 6 the manipulating handle 32 is grasped bythe hand of the operator and the shaker moved back and forth resultingin an oscillatory inoreinent the grate.

The flange 18 is provided with a slot 20 which receives the handle Whenthe receptacle is fully inserted in the ash pit.

The ash-pit S and the receptacle 1% are adapted to remain on the store,when the store is being used either as a coal store or a wood burningstove. hen it is desired to conrert the store from a coal store, asshown in the drawings, into a Wood burning stove, the fire-pot isreinored and the grate removed from the fire-pot and placed Within theopening D in the store bottom, and the stove is then used as an ordinarywood burning stove.

Having thus describedinyinventioinwhat I claim as new is:

A Combination Wood and coal store including a bottom having an opening,a downwardly tapered fire-pot mounted upon the bottom of the etove andsurrounding the said opening and having an interior gratesupportingflange at its lower end and also prorided thereat n'ithineans fordetachably securing the fire-pot t0 the store, a grate of a size to fitthe flange of the fire-pot and the opening in the bottolnof the store toenable it to be used in the fire-pot or in the opening of the bottom ofthe store when the fire-pot is lGll'lOYQCl, said grate being alsoprovided with a depending lug, an ash pit secured to the bottom of thestore and projeeting in advance of the same. and a handle connected withthe lug and ext-ending over the top of the projecting portion of the ashpit.
